Specification of Letters Patent.

Patented Mar. 23, 1915.

To all wiwm it may concern Be itknown that we, (1) FRANK SARDYN- SKI and(2) JOHN TYszKo, (1) asubject of the Czar of Russia and (2) a citizen ofthe United States of America, residing at Amsterdam, in the county ofMontgomery and State of New York, have invented certain new and usefulImprovements in Life-Boats, of which the following is a specification.

This invention relates to new and useful improvements in life boats.

The primary object of the invention is to provide a life boat which maybe filled with passengers when positioned upon the deck of a vessel andmay be either launched into the water or allowed to be floated upon thesinking of the vessel, the boat comprising a water-tight inclosure forthe passengers.

A further object is to provide an inclosed life boat which iswater-tight rendering the same incapable of sinking, the same having amovable car which maintains its normal equilibrium regardless of therocking or other movements of the boat.

A still further object is to provide a floating spherical casing with apassenger car mounted upon rollers therein, for maintaining its normalequilibrium and having means whereby the passengers may look out of thetop windows of the boat and may enter and leave the same through a sidedoor thereof.

'With these general objects in view and others that will appear as thenature of the invention is better understood, the same consists in thenovel combination and arrange ment of parts hereinafter fully described,illustrated in the accompanying drawings and pointed out in the appendedclaims.

In the drawings forming a part of this application and in which likedesignating characters refer to corresponding. parts throughout theseveral views :Figure l is a side elevation of the device. Fig. 2 is atop plan view thereof. Fig. 3 is a central vertical sectional view ofthe same. Fig. 4: is a horizontal sectional view taken upon line IV-IVof Fig. 3, and Fig. 5 is an enlarged detail view partly in section ofone of the passenger car mounting means.

, It will be noted that the present boat is designed to be positionedupon the deck of a vessel and to be employed for saving the lives of thepassengers in the event of an accident or sinking of the vessel and suchlife boat broadly consists of the hollow spherical casing 10 having anannular deck 11 supported at opposite projecting portlons 12 by means ofbrackets 18, it being. understood that the deck is positionedabove thenormal water line of the boat and the horlzontal axis or diameter of thecasing. A car is positioned within the casing consisting of a basket 14having its sides parallel to the adjacent inner walls of the casing 10and being slightly greater than a hemisphere. form of an outwardlyprojecting normally horizontally positioned flange is carried by theupper edge of the basket while a lower An annular platform 15 in thedeck 16 is provided in the basket for sup- 7 porting the passengers oroccupants, such lower .deck having a trap door 17 therethrough leadingto a chamber 18 therebeneath. V

-A plurality of windows 19 are positioned. v a

in the top of the casing-10 while a vertically positioned pole 20centrally carried by the lower deck 16 is provided with cross rounds 21thus forming a ladder by means of which the passengers ascend to thewindows 19 for the purpose of lookingout of the boat. The casing 10 hasan outside door 22 and by means, of which persons may freely pass fromthe outer deck 11 to the inner platform 15 and vice versa while a ladder23 alfords a means for allowing communication between the platform15 andthe lower deck 16.

The basket is shiftably supported within the casing by means of aplurality of legs 24 which are radially arranged upon the outer side ofthe basket and have outer 'oortions 25 connected by suitable swivels 26with the main portions of the legs, while rollers 27 are journaled inthe free ends of the said outer portions 25. The upper end of the pole20 is also provided with a swiveled portion 28 having a roller 29journaled therein for engaging the adjacent surface of the inner side ofthe casing.

From this detailed description of the invention it will be seen thatwhenever desired, the door 22 of the boat may'beopened and persons mayfreely pass from the outer deck 11 to the inner platform 15 and by meansof the ladder 23 may descend to the lower deck 16 and when the door isclosed, the boat will be water-tight and will completely protect theoccupants thereof. The mounting of the basket 14 upon the rollers 27insures a maintenance of the equilibrium of the basket as the lower deckupon which the occupants are positioned is below the center of gravityof the basket so that the lower deck normally remains horizontalregardless of the movements of the casing 10 during the rockingmovements of the boat in the water. The outer deck acts as an outriggerfor preventing the boat from capsizing while the brackets 13 provide aform of stern and bow keel members.

While the form of the invention herein shown and described is what isbelieved to be the preferable embodiment thereof, it is nevertheless tobe understood that minor changes may be made in the form, proportion anddetails of construction without departing from the spirit and scope ofthe invention as set forth in the appended claims.

What is claimed as new is z 1. A life boat comprising a sphericalcasing, an annular projecting deck carried thereby, a passenger basketwithin the said casing substantially hemispherical in form, an annularlyprojecting platform provided at the upper edge of the said basket, andswivelly mounted rollers carried between the said basket and the innerside of the casing.

2. A life boat comprising a spherical casing, a side door and topwindows providedfor the said casing, a projecting annular outer decksecured to the said casing above the normal horizontal axis thereof andhaving opposite projecting portions, bracing brackets connecting'thelower sides of the said projecting portions and the outer side of thecasing, a passenger basket positioned within said casing, a platformsecured to the upper edge of the said basket, a lower deck positionedwithin said basket below the center of gravity thereof, a ladder betweenthe said platform and lower deck, a ladder centrally carried by the saidlower deck and extending adjacent the said casing windows, rollermounting means between the said basket and casing, and a casing engagingswiveled rollers carried by the free end of said centrally carriedladder.

3. In combination with a life boat, a nor mally horizontally positionedpassenger basket substantially hemispherical in form positioned in saidboat, a passenger deck within said basket, an outwardly projectingannular platform carried by the upper edge of the said basket, radiallypositioned legs secured to the outer side of the basket, outer legportions swiveled to the said legs, and bearing rollers journaled in thesaid outer portions and engaging the interior of the boat.

In testimony whereof we affix our signatures in presence of twowitnesses.
